BOTTLE-FILLING DEVICE.

Specification of Letters Patent. Patentedl Aug. 10, 19150 Application filed December 15, 1913. Serial No. 806,744.

To all whom it may concern:

Be it known that I, JOSEPH H. GODFREY, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Bottle-Filling Devlces, of which the following is a specification.

This invention relates to devices for filling bottles and similar receptacles with liquid, and has reference more particularly to that type of filling mechanism wherein a valve controlling the flow of liquid to the bottle is opened through the agency of an electromagnet when the empty bottle has been sultably positioned relatively to the filllng device to receive the liquid, and is subsequently closed by the automatic deenergizing of the magnet to cut off the flow of liquid tothe bottle when the latter has been filled to the proper or desired height.

The device of my present inventlon is of the same general character as the bottlefilling device disclosed in Letters Patent No. 1,011,184, granted December 12, 1911 to myself and Leslie J. Housel; but embodies some improvements upon the mechanism of said patent in the directions of increased simplicity of construction, an lmproved construction requiring less head room between the bottom of the liquid tank and the mouths of the"bottles, greater reliability and efiiciency in operation, and reduced cost of manufacture and maintenance.

With the above stated objects in view, the

invention consists in the matters hereinafter described and more particularly pointed out in the claims.

The invention will be readily understood when considered in connection with the ac companying drawing, which illustrates one a practical mechanical form in which the same may be embodied, and in which the figure is a vertical section through a liquid tank, a delivery spout and valve, and-my lmproved automatic mechanism for controlling the operation of the valve; it being understood that in practice the tank shown may and usually will have a plurality of delivery spouts and valve-controlling mechanisms which are duplicates of that shown.

My present improvements relate chiefly to automatic means for controlling the flow of the liquid from an over-head tank or resera valve-controlled delivery opening in the bottom thereof into the open upper end of a bottle; and these improvements are herein illustrated as applied to a machine for filling milk bottles, although it will be understood that the kind or character of the fluid handled by the machine is entirely immaterial to the invention itself.

In the drawing 5 designates atank or reservolr which may be assumed to contain a body of milk to be delivered into a bottle 6. In the bottom wall of the tank 5 is secured a depending delivery spout 7 terminating in a concave bell or hood 8 which serves as a guide or centering device for the registry of the mouth of the bottle with the lower end of the spout in a manner well unders,

stood. The lower end of the spout 7 is bev-- eled to form a valve-seat 9, with which co operates a valve 10 formed on the lower end of a tubular valve-stem magnetic material that extends upwardly entirely through the tank and the top wall of the latter and at its upper. end is connected to the tubular armature 12 of an electro-magnet 13. The magnet 13 is mounted directly upon the top wall of the tank 5, and

11 formed of non the armature 12 has on its upper end an annular flange 14, between whichand the top of the magnet is a coil compression spring 15 by which the valve 10 is normally held to its seat 9. i The energizing of the magnet draws the armature 12 downwardly, thereby opening the valve 10, as shown by lines. 7 Below the valve 10 is a ball-float 16 havmg a long stem 17 that extends upwardly centrally through the tubular valve-stem 11 and armature 12, and is guided at its upper end by the horizontal arm of an anglebracket 18 that is mounted on thespool of the magnet 13. On the upper end of the float-stem 17 that serves the double function of a circuitswitch and an of a light coil spring 20, the lower end of which is stepped on the bracket 18. The spring 20 exerts a limited lifting effect upon the ball-float 16 and its stem 17, and also serves to form a part of an electric circuit between'the switch-arm 19 and the bracket 18. This spring, however, is so light that, when the ball-float 16 is wholly unsupported by liquid in the bottle 6, the weight of the ball-float and its stem draws the switch-arm 19 down into engagement with a contact 21 that is mounted upon and insulated from the bracket 18.

Secured to the front wall of the tank near dotted is a horizontal pin or bar 19 abutment for the upper end by a link 26 (suitably insulated therefrom) its lower end through suitable insulation 22 i is a contact member 23, and, below thesame,

a lug with a' curved trigger 27 which latter is hung from a pivot lug 28 on the bottom wall of the tank 5 and'swings through'a radial slot 29 formed in th' hell 8.. A leaf spring 30 normally separates the switch-arm 25 from the contact 23 and maintains the trigger 27 inwardly of the slot 29 of the bell 8, as shown by dotted lines.

' At 31 is indicated a battery or other source of electric current; and the circuit from one pole of the, battery comprises a Wire .32, lug 24, switch-arm 25,'contact 23,

a wire-33 connecting contact 23 with'a binding post 3-1 on the top of the tank, the wind, ing of themagnet 13,;a wire'35'from the upper 'end of said-winding to the contact member 21,- switch-arm '19, spring 20, bracket 18, the spool of the magnet 13, the

metal frame of th tank, and a return wire spout. I

extendsinwardly In the idle position of the parts, the valve 10 is, of course, closed, the float. 16 isin the lower or dotted line, position indicatedin thev drawing,' the, switch 19 is in the. closed dotted line position,

0 dotted line-position, and the-trigger 2 is in the dotted When an, empty bottle is brought into registry with'the hellf8, as shown, the mouth of the bottle strikes the trigger 27 and forces switch 25 and the same outwardly, thereby closing, the.

j completing the circuit; f through the magnet 13. This at once draws the armature 12 and valve 10 downwardly to the dotted line'position's' indicated, and

the liquid flows into the bottle andifills the 'same' to a point at which it raises the float 16 to anextent'suflicie'nt to .open the circuit at'19, 21. The magnet 13 'is thereupon de- Y energized,

and'the spring 15 at once closes the valve 10 shutting ofl further flow of the liquid "to 'the'bottle. "Upon the'removal of the bottle, the spring opens the switch 25 slightly before the switch. 19 drops intoen- "g g me t.
